I emailed American Eagle last week to ask about who designs their in-store music, since it is now my dream job. Here is their response to me:

Dear Nicole,

Thank you for your recent email.

The position you are inquiring about is actually a combined effort of
several members of our Marketing team. Unfortunately, we are unable to
provide more exact details since this position is not delegated to one
person. We apologize for any inconvenience.

Thank you for your interest in AE.

Sincerely,
Your Friends @ AE

Ok, not very informative, but at least I know there is more than one person in the world involved in doing this! My prospects at this kind of work have increased dramatically (up from 1 to 5 in a million). And I have friends at AE!
